VALVE.

Specification of Letters Patent.

?atent. May 31, 1910.

Applications filed October 29,. 1908. Serial No. 525,272.

To all whom it may concern:

Be it known that I, SAMUEL E. Mo- Kmorrr, a citizen of the United States, residing at Lohn, in the county of McCulloch and State of Texas, have invented certain new and useful Improvements in Valves, of which the following is a specification.

This invention relates to that class of valves which are employed in connection with tanks, to controlthe filling thereof, and which are automatically closed by a float lever; and it is the object of the invention to rovide a valve of this kind which is simp e operatlon.

Another object of the invention is to rovide a valve which can be readily applied to the supply-pi e of the tank.

Another objec is to provide a structure in which the valve pro or has a sliding movement toward and rom its seat, the valve being so mounted, and engageable b the float-lever, that a positive closure is e fected.

With these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter described and claimed, reference being had to the drawing hereto annexed, in which- Figure 1 is an elevation of the valve, the bottom of the tank to which it is applied, being shown in section. Fig. 2 is a central vertical section of the valve. Fig. 3 is a section on. the line 33 of Fig. 1.

in the drawing, 5 denotes the valve-body,

the same having an opening 6 through which the water flows. One end of the opening is counterbored, and-screw-threaded, so as to screw on the supply-pipe 7 of the tank, the bottom of which is indicated at 8. The other end of the valve-body forms a seat for the valve proper. The pipe 7 extends through an opening in the tank bottom 8, and the valve-body is screwed down against the said bottom, a gasket 9 being interposed therebetween, to make a water-tight joint.

The valve roper is a disklO, which is faced with a disk 11 of rubber or other suitable material to engage the seat. The disk in construction, and efiicient in' 11. on its seat. The valve-body is encircled by a band 18, having at its ends outstanding ears 19, through which passes a screw 20, for drawing the ears together, and thus clamping the 'band on the valve-body. The guide 13 is an upstanding continuation of the cars 19. The head 17 engages the disk 10 at its center, so that the disk 11 is held squarely to its seat. The arm 12, although sufliciently loose on the guide 13 to slide freely up and down thereon, is not loose enough thereon as to permit the valve to tilt forwardly, rearwardly or sidewise, thus assuring its seating squarely, and effecting a tight closure at all times. \Vhen the disk 11 becomes Worn, it can be removed, and renewed.

In operation, when the water level in the tank drops sufiiciently so as to permit the lever 15 to swing in a direction to release the valve, the head 17 then moving away from the disk 10, the latter is pushed upwardly by the pressure in the pipe 7, and the valve is thus opened, and the water flows into the tank. When the float is elevated by the filling of the tank, the head 17 is forced downwardly against thedisk 10, and the-latter is moved to its seat, and held thereon, thus shutting off the water. The disk moves in a right line toward and from the seat, and its being properly seated'is thus assured.

A valve constructed as herein described is devoid of complicated parts to get out of order, and it can be readily applied. The valve-body serves as a reducer, and by making it in different sizes, it can be fitted to different-sized pipes. The band 18 is adjustable on the valve-body, so that the floatlever may be placed in the most convenient position within the tank.

I claim:

1. A valve comprising a body having a seat at one end, a guide carried by the body, a disk eiwageable with the seat, an arm on the disk having an opening to receive the guide, said arm being slidable on the guide in a right line toward and from the seat, and a float lever engageable with the back of the disk.

2. A valve comprising a body having a seat at one end, a disk engageable with the seat, a band encircling the body, and adjustable thereon, standards rising from the band, an arm on the disk havin an opening to receive the standards, sai arm being slidable on the standards toward and from the seat, and a float lever fulcrumed on the standards, and engageable with the back of the disk.

3. A valve comprising a body having a seat at one end, a disk enga eable with the seat, a band encircling the ody, ears projecting from the ends of the band, a. clam ing means passing through the ears for a justably securing the band on the body, standards rising from the ears, an arm on the disk hav1 ng an opening to recei've the standards, 'sald arm being slidable on the standards toward and from the seat, and a float lever fulprumed on the standards, and 15 engageable with the back of the disk.

11 testlmon whereof I aflix my signature in presence 0 two witnesses.
